“…16. Subsequently, a totally different imaging system, called computational compound eye (COMPU-EYE) (Lee et al 2016) was proposed for improving the resolution. The CurvACE is inspired by Drosophila and composed of a microlens array, a neuromorphic photodetector array and a flexible PCB.…”

An artificial compound eye system is the bionic system of natural compound eyes with much wider field-of-view, better capacity to detect moving objects and higher sensitivity to light intensity than ordinary single-aperture eyes. In recent years, renewed attention has been paid to the artificial compound eyes, due to their better characteristics inheriting from insect compound eyes than ordinary optical imaging systems. This paper provides a comprehensive survey of the state-of-the-art work on artificial compound eyes. This review starts from natural compound eyes to artificial compound eyes including their system design, theoretical development and applications. The survey of artificial compound eyes is developed in terms of two main types: planar and curved artificial compound eyes. Finally, the most promising future research developments are highlighted.

“…Simultaneously, further advances should be made to address the remaining challenges of current research, such as the problem of low resolution. Opportunities also exist to extend the concepts described above to the mechanical deformation of high‐density photodetector arrays or to exploit digital signal processing techniques …”

“…Visual prostheses are classified as follows: (i) an epiretinal prosthesis that is attached to the GCL to directly stimulate the RGC (blue dashed box in Figure a, right) and (ii) a subretinal prosthesis that is inserted between the ONL and retinal pigment epithelium to stimulate the bipolar cells (red dashed box in Figure a, right) . These two types of visual prosthesis are applied via clinical treatment and lead to improved vision in daily life . Additional detailed information about epiretinal and subretinal prostheses can be found in other review papers …”

The diverse vision systems found in nature can provide interesting design inspiration for imaging devices, ranging from optical subcomponents to digital cameras and visual prostheses, with more desirable optical characteristics compared to conventional imagers. The advantages of natural vision systems include high visual acuity, wide field of view, wavelength-free imaging, improved aberration correction and depth of field, and high motion sensitivity. Recent advances in soft materials, ultrathin electronics, and deformable optoelectronics have facilitated the realization of novel processes and device designs that mimic biological vision systems. This review highlights recent progress and continued efforts in the research and development of bioinspired artificial eyes. At first, the configuration of two representative eyes found in nature: a single-chambered eye and a compound eye, is explained. Then, advances in bioinspired optic components and image sensors are discussed in terms of materials, optical/mechanical designs, and integration schemes. Subsequently, novel visual prostheses as representative application examples of bioinspired artificial eyes are described.

“…The artificial compound eye imaging systems still have the low‐resolution problem in comparison with previous cameras with a single lens due to their small size and low ommatidial density. The next goals of biologically inspired light imaging system go toward the enhancement of image resolution and sensitivity in an ultrathin scale in order to prevent crosstalks between waveguides and also to elaborate a postimage processing method . Furthermore, biomimetic devices inspired by superposition eyes and tunable biomimetic imaging lenses are still under development.…”

Biological wonders, found in insects such as antireflecting moth eyes, compound eyes in a honey bee, firefly lanterns, and iridescent butterfly wings, inspire human beings for advanced light imaging and illumination technologies. Dazzling advances of micro-and nanofabrication technologies allow insect-inspired structures, for example, artificial compound eyes with a wide field of view and low aberration, bioinspired light-emitting diode lenses, and structural coloration templates, featuring miniaturization. Besides, plasmonics and metamaterials offer an unprecedented approach that overcomes the diffraction limit and unveils unknown optical phenomena in ultrastructures inspired by insects. Here, insect-inspired photonic structures for light imaging, light extraction, and structural coloration are reviewed, and photonic functions and structure fabrications inspired by insects that can be applied in advanced imaging and illumination applications are discussed.
